Seiko 'Jumbo' Automatic Chronograph

In the late 1960's and early 1970's, Seiko was experimenting with some of the first automatic chronograph movements ever made.

Unlike the Swiss, who were creating their own automatic chronographs in the form of the Heuer-designed Chronomatic and the Zenith El Primero, Seiko — being used to producing in scale — were able to keep their costs for their chronographs more accessible through mass production. Featuring a wide variety of case and dial designs, the 1970s were very much the golden age of Seiko sports watches. 

This particular automatic Seiko chronograph is a classic ‘Jumbo’ Reference 6138-3000 from circa the early 1970s. Housed in a 42mm stainless steel cushion case with a mineral crystal, barrel pushers, and a polished faceted bezel, it features a matte black Tritium dial with a raised outer chapter ring and a dual-register chronograph, a matching handset, and a day-date display. Powered by the famed Caliber 6138 movement, it comes paired to a cool, stainless steel multi-link bracelet with a signed blade clasp.

To misquote the Bard, ‘a watch by any other name would be many times as expensive.’ So whether you’re just getting into chronographs or you’re a Seiko die-hard, you owe it to yourself to give this Jumbo a whirl.

For over 140 years, Seiko has been cranking out innovative and impeccably engineered watches at every price point, from entry-level Seiko 5s to world-class haute horlogerie pieces under the Grand Seiko brand. Underpinning the company’s efforts has been the mass production of reliable and accurate movements paired with a wide array of case and dial configurations.
Founded in 1881 by clockmaker and businessman Kintarō Hattori in Tokyo, Japan as “K. Hattori,” Seiko began importing Western timepieces and selling them in the local market. In 1892, Hattori changed the name of the firm to Seikosha (“house of exquisite workmanship”), which was further altered to “Seiko” in 1924. Following the Second World War, during which Seiko produced watches for the Japanese military, the company began its streak of innovations based upon affordable, in-house movements and Japanese savoir faire. These included myriad dive watches such as the famed 6105 and the fan-favorite 6139 chronograph.

Later, in 1969, Seiko would go on to produce the Astron, the world’s first quartz watch. This technological innovation was followed by the Seiko Kinetic in the 1980s, which married quartz accuracy with automatic, self-powering functionality. Today, Seiko’s product offerings are vast, including dress watches, dive watches, chronographs and much more, all of which are powered by in-house movements comprising different types of technology.

Despite a move toward luxury positioning and pricing in the brand’s modern offerings, vintage Seiko classics can still be had at incredibly reasonable prices today, making them a favorite entry point into the vintage watch world for myriad collectors. From their availability in post exchanges on military bases around the world to their fame from films such as Apocalypse Now to their presence at six Olympic Games, Seiko watches are deeply ingrained in the consciousness of the contemporary collector.
